This data release provides FLAMES/UVES spectra observed as part of the ESO program 112.25ES.001 (P.I. P. Kervella) with the main scientific goal of estimating interstellar extinction of 16 Galactic Cepheid variable stars. For this purpose, neighbouring field stars of the Cepheids were observed, queried from the Gaia Data Release 3 catalog, with the FLAMES multi-object spectrograph. The instrument setup was such that, on average, 115 field stars were observed with the GIRAFFE spectrograph in MEDUSA mode and 2-7 field stars with the UVES spectrograph in the Red Arm mode. This release covers only the UVES data, as the ESO automatic reduction process covered the GIRAFFE spectra, which are available for download from the ESO Science Portal. The fibers fed to UVES have a diameter of 1 arcsec, and the cross-dispersed echelle spectroscopy provides a spectral resolving power of R=47,000.
